IMPROVEMENT INIDEVIGE FOR OOQLINGMILK.

TO ALL WHOM IT MAY CON CERNi Be it known that we, LEWIS T. IIAWLEYLefthe town of Salina, in the county of Onondaga, and State of New York,and AMOS WESTCOTT, of the city et' Syracuse, inthe county and Stateaforesaid, have invented a new and improved Mode and Device for CoolingMilk or. other fluids in jars or vessels, and for transferring suchuidswith an improved meter and dipper.

Our invention consists essentially in the employment, in. connectionwith milk-dans or jars of the ordinary construction, of a reservoir andits attaehment,`for the purpose of holding iee or cold Water, and alsoof a dipper and meter to transfer the fluid from' the yeanfto anothervessel. l p

In the constructionof this reservoir, -we make a'vessel corresponding inshape with the curb of the jar er can,l so that when snugly fitted intothis curb it constitutes a perfect stopper, and in this regard becomes asubstitute -for the'ordinary cover of'- the can.A To the bottom of thiscover' or stopper there is attached a tube, running down into the can,opening into the stopper and made water-tight, the whole of which, saidcap-stopper and tube, forms a receptacle for ice or cold water. Thelength and size of this tube may be varied according as cooling-surfaceand material are desired, but-generally about one-fifth of the diameterof the can, and twothirds its depth. This stopper and tube are shown inthe annexed drawings at A. in Figure 2.

In order to increase the refrigerating powers of the -vesseL-as abovedescribed, we encase the can or jar with ajackct of felt or othersuitable covering, which is saturatedwith water. The cold produced bytheevaporation on the surface aids materially to produce the objectdesired. i

It is'well known among dairymen that mill: taken .from the cow with allits animal heat, and placed in large cans, and transported a longdistance, either to the city market or to the factory, often, especiallyin warm weather, becomes much deteriorated, and sometimes entirelydestroyed for the purpose of making goed butter or cheese. I I

Theinventors claimthat the device above described aiords a perfectremedy, and thatwi-th milk-cans thusceirstructed and provided, milk maybe kept a long;` time, and may be transported a long` 'distance withoutimpairing its quality or avor. s u

When desirable to retain the ice for'a long time, we make the collarofthe stopper A, in iig 2, with double walls, and fill the intermediatespace with pulverized charcoal or other non-conducting material.

We cover the stopper A, in iig.,2, which is the icq-reservoir, with thesupplemental cover B, as shown in Figure 3. This cover is provided witha knob -on the coll-nir thereof, as shown at in iig. 3,-and also a.correspending knob opposite thereto, so that a gentle pressure will'spring these knobs below the rim of the vessel to be covered, and thushold the cover securely and snugly to ilsplace. l

We are aware that covering of clot-h has been used on tinrand othervessels for the purpose of cooling fluids contained therein, by means ofevaporation, and we therefore claim no patent for that; but

` What we do claim as our invention, and desire to'seeure by LettersPatent, is-

1. The felt jacket or covering, of other suitable material, incombination with the stopper and ice-reservoir A, arranged substantiallyas and for the purpose above set forth. l

2. We claim the reservoir for ice or cold water A; constructed A andarranged substantially as above described, and for the purposeabovespecied.

3. ,We claim the knobs on the collarl of the cover, substantially asand'for the purpose above set forth.
